근대 5종 선수의 글루타민 섭취가 혈중 글루타민과 근피로 생체지표에 미치는 영향 The effect of glutamine ingestion on plasma glutamine and biomarkers of muscle stress in modern pentathlon athletes
The purpose of this study is to identify the effects of intake of glutamine on changes in glutamine, ammonia, lactic acid and creatin kinase(CK) in the blood after prolonged exercises with sub-maximal intensities targeting modern pentathlon athletes. 14 male modern pentathlon athletes were selected randomly as subjects of this study and were divided into a group of treatment with glutamine(Glu-G) and a group of no treatment(Con-G). The treadmill exercise was carried out at 75% VO2max for 90 min.Incase of Glu-G, 100mg․kg-1 of glutamine was given in a day for 7 days and the following conclusions were obtained. The level of glutamine in the blood after the treadmill exercise was significantly higher in Glu-G than that in Con-G(p<.01) and ammonia in the blood after treadmill exercise was significantly lower in Glu-G compared with that in Con-G(p<.001). The level of lactic acid and creatine kinase in the blood was significantly lower in Glu-G compared with that in Con-G(p<.001 and p<.01, respectively).The conclusion was drawn in which intake of glutamine gave the positive effect on reduction of muscle fatigue. Since it was confirmed that intake of glutamine gave the positive effect on reduction of CK in the blood, it was thought to consider the intake of glutamine in order to reduce the muscle damage.
